Ethereum announced the public Platåberget testnet on Aug. 17 as an early environment for testing the Glamsterdam fork scheduled for Aug. 20; the network will run for several months with a publicly joinable validator set and optional client releases. The test focuses on protocol updates including enshrined proposer‑builder separation, block-level access lists, gas repricings targeting roughly a 200 million gas floor, a separate state-gas meter that means plain ETH transfers may not always be 21,000 gas, and larger contract/initcode limits to surface compatibility issues for wallets, validators, indexers and DeFi tooling ahead of Sepolia, Hoodi and eventual mainnet, supporting security and broader crypto adoption.
See what traders are focused on
Ethereum has announced the public Platåberget testnet, describing it as an early testing environment for the post-Glamsterdam network changes. In its Aug. 17 announcement, the Ethereum Foundation said the network is intended to run for several months before Glamsterdam moves to longer-lived testnets.
The Foundation said the testnet offers an opportunity for application developers, wallet teams, indexers, validators and builders to test software against changes expected in the upgrade. It scheduled the Glamsterdam fork on Platåberget for Aug. 20.
Gas assumptions are a key testing target
The announcement specifically warned that tools relying on a hardcoded maximum gas limit will need updating. The proposed gas repricings aim at a roughly 200 million gas floor, according to the post, while the wider changes affect how software estimates and handles transaction costs.
The Foundation also said that creating an account, deploying code or writing a new storage slot would be metered through a separate state-gas dimension in the test environment. It cautioned that a plain ETH transfer would not always be represented by a flat 21,000-gas assumption.
What else is included
The published list highlights enshrined proposer-builder separation, block-level access lists, gas repricings and larger contract and initcode limits. The Foundation described these as changes spanning the consensus and execution layers.
Platåberget has a publicly joinable validator set, and the post directs users to its ret releases remain optional, with temporary container images listed while client teams prepare releases
Next testing steps
The Foundation said the network is meant to surface downstream compatibility issues before a non-finality devnet and, later, upgrades on Sepolia and Hoodi. Mainnet activation remains a later step after those testing stages are stable.
For now, the announcement is a testnet notice rather than a mainnet launch. Teams with gas estimation, transaction construction or block-production software are the audience the Foundation singled out for early testing.
